IMPROVEMENT IN SASH-HOLDERS.

The Schedule referred to in these Letters Patent and making part of thesame.

Be it known that I, RoBnRTB. HUGUNIN, of the city, county, and State ofNew York, have invented a new Window-Sash Supporter, of which thefollowing' is a specification.

Nature and 'Objects of the Invention.

This, invention consists in the combined use of two rollers, a lever,and two springs attached to-and working from a front fasteningplatethetwo rollers .suspended in bearings in the lever, so as to movefurnishing friction when the sash is stationary, and

llessening the wear of' the rollers'. n

General Description.

A, fastening plate, to which' the lever, springs, rollers, 85e., areattached before the `same is secured in the casing ofthe window.

B, movable leverfor conning the rollers, by means of the springsadjustingVv them to each other and the spacebetween the sashrand casing.

C, horizontal spring,\one end resting in a springsocket projection,extending `back from the front side of -plate A, and the other endsupporting and controlling the lI'novable end of the lever B, and'furnishing the necessary pressure to the rollers.

D, vertical spring attached to the end of the lever B, and by means ofit controlling the vertical movements of one of the rollers.

This spring is confined between .projections on the end of the lever andfrom rear-,side oi' plate A.

E, lever securing pin, passing through the projections from plate A overthe lever, so as to cornh'ne it and at the same time allow i-t. to moveunder the influence ot thev springs, as required.

F, upper semi-elastic roller, with bearings in lever, .allowing it torise up and down.

G, lower semi-elastic roller, with bearings confining itto a fixedposition in the lever, and moving only with it by the elasticity of thevertical spring.

H and H', projections on the rear side of the plate A tor support theroller F and the weight of the sash.

These projections hold this roller and, allow the other one to be drawnfrom it by the yielding of the spring D in pressing the sashdown, &c.

I and I', fixed bearings in lever B for confining roller G.

J and VJ' open bearings for confining in a movable position the rollerF.

The space between the bearings I and J is greater than the diameter ofthe roller, allowing them, by

the lifting of F, to roll clear of each other in raisingr the sash.

K, projection from plate A, for confining securely one end ofthevertical spring D.

' Y L, spring-seat projection extending back from front -side of'plate Ato a depth requiredto take in the spring'.

M, projection from one end of lever-B, which is passed through theopening in plate A from the rear to the front, and over the spring C, onwhich it rests,

Ifollowing the rollers back and .i'orth with the lever,

according to the space ing, &c.

' When the sash is at rest the two rollers are in contact with 'eachother, and in turning the motion of the rollers is opposite at point ofcontact, and in this way the friction is furnished to support the sashin position lei't; aproper and eficient spring pressure being, ofcourse, preserved to prevent the sliding 'of the rollers, &c`. l

.In pulling down the-sash the upper roller catches on the projections Hand H', and is held there, while the lower' one, suspended by thevertical spring D, is drawn down sufficiently by the additional pressureand friction, from the upper roller to enable them both to turn, 82o.

between 'the 'sash and cas- Claims.

1. rIhe sliding lever B, in combination with the vertical spring l(L andhorizontal spring D, substantially as setforth.

2.,'lhe 'plate A, having the confining-projections K and L and pin E,with the springs C and D, in combination with the lever B and rollers Fand Gr, substan tially as described.
